About the Product

Enhance Your Beverage Experience with the Pentair CTO-20 Cartridge from Coffee Machine Depot USA

As the authorized distributor of Pentair products, Coffee Machine Depot USA proudly presents the Pentair CTO-20, a revolutionary 20-inch drop-in cartridge designed to elevate your beverage quality by significantly reducing sediment to 0.5-microns and diminishing chlorine, taste, and odor. This high-capacity filter cartridge offers an impressive flow rate of 3.0 gallons per minute (gpm) and is capable of treating up to 30,000 gallons of water, ensuring your beverages are consistently pure and delicious.

System Advantages: Elevating Beverage Quality and Reducing Operational Costs

  • Enhanced Beverage Quality: The Pentair CTO-20 cartridge ensures that both cold and hot beverages taste better and are of consistent quality by improving water clarity and purity.
  • Reduced Maintenance: By decreasing the frequency of maintenance and extending the lifespan of equipment, this cartridge offers significant cost savings and operational efficiency.
  • Advanced Filtration Technology: Featuring gradient-density depth filtration, it effectively removes dirt, rust, and debris as small as 0.5-microns, while activated carbon filtration eliminates chlorine taste and odor, protecting equipment from corrosion and wear.
  • Cost-Effective: The high capacity of the Pentair CTO-20 cartridge reduces the need for frequent replacements, making it a more economical choice over proprietary quick-change filters. Additionally, it generates less waste, as only the cartridge needs replacing.

It's compatible as a retrofit option for most standard 20” drop-in style housings.
